摘要:
A speed change detection apparatus includes an image carrier for carrying a latent image, and a latent image pattern forming device for forming a latent pattern image on the image carrier. The pattern image includes periodically formed line or dot images. An alternating current conversion type surface potential sensor is provided to detect a potential of the surface of the photoconductive member. The alternating current conversion type surface potential sensor further detects a change in speed of the image carrier by detecting a moiré appearing on the latent image pattern.

Disclosed is an image forming apparatus including a first member having a surface endlessly moving in a specific direction a second member having a surface endlessly moving in the specific direction at a region facing the surface of the first member, and a supporting member holding the second member and to move together with the second member. The supporting member includes a release mechanism to release an engagement of the supporting member from the second member. A pressing member is included to press the second member via the supporting member to cause the second member to contact the first member under pressure to form a nip between the first and second members. The release mechanism releases the engagement of the supporting member from the second member when the second member is pushed away by a leading edge of a recording medium having a thickness greater than a reference thickness value.

摘要:
An image forming apparatus includes an image forming unit to form an adhesive toner pattern in a predetermined bonding range of a sheet, outside a printable range in which an image according to image data is formed, a stacking unit to stack multiple sheets one on top of another, and a sheet binding device that includes a fusing device to fuse and fix the adhesive toner pattern formed on the multiple sheets to bind the multiple sheets together, and a bonding strength setting unit to determine, in accordance with a desired bonding strength, at least one of a number of color toners used for forming the adhesive toner pattern, a bonding manner, a number of pixels of the adhesive toner pattern, a toner area ratio of the adhesive toner pattern, and a layer thickness of the adhesive toner pattern.
摘要:
A temperature controlling method and apparatus for a thermal printhead, in which a temperature of a thermosensitive recording material is detected by measuring a temperature change of the thermal printhead when a surface of the thermosensitive recording material contacts a surface of the resistant heater of the thermal printhead. The thermosensitive recording material is heated by the thermal printhead to a temperature suitable for recording or erasing an image on the thermosensitive recording material, with the temperature suitable for recording or erasing the image being changed as a function of the detected temperature of the thermosensitive recording material.
摘要:
A recording and erasure of a visible image on a reversible heat-sensitive recording medium can be repeatedly performed in a stable condition without failure. The visible image is recorded by a thermal recording head on the reversible heat-sensitive recording medium. The recording medium is provided with an unheated area which is not exposed to heat. The visible image is erased by providing heat by a thermal erasing head. The reversible heat-sensitive recording medium is provided with an unheated area which is unheated by the thermal erasing head. The unheated area substantially extends along at least one of sides of the reversible heat-sensitive recording medium. The unheated area prevents the reversible heat-sensitive recording medium from being warped when a erasing operation is repeated many times.
摘要:
A reversible thermosensitive recording medium having a support, a reversible thermosensitive recording layer formed thereon which contains a matrix resin and an organic low-molecular-weight material dispersed in the matrix resin, capable of reversibly assuming a transparent state and a white opaque state depending on the temperature thereof, and a magnetic recording layer formed on the reversible thermosensitive recording layer, and optionally, an anchor layer, which is provided on the reversible thermosensitive recording layer. The magnetic recording layer is integrally provided in a part of the reversible thermosensitive recording layer or the anchor layer by a step of fusion-bonding, applying, or transferring.
摘要:
A reversible thermosensitive recording material which includes a support, and a thermosensitive layer provided on the support and including, as main ingredients, a resin matrix and an organic low molecular weight substance dispersed in the resin matrix, wherein the transparency of the thermosensitive layer reversibly changes depending on the temperature thereof is characterized in that the rate of change in heating temperature for the initiation of transparentization is 13% or less, the rate of change in transparency is at least 50% or the rate of change in film thickness is at least 2%. By heating the reversible thermosensitive recording material, the formation and erasure of images may be suitably effected.
